OK, this is one for all the Dahlia experts. I have asked this before in a general post, but I'm still not a hundred percent sure what to do - so I'll ask again...
I bought these dahlias when they were fully grown and in flower from a local garden centre, in other words, I did not grow them from a tuber. They are now coming to the end of flowering, and I am not sure what to do with them. Will there be tubers in those pots - and should I root around until I find them. Or should I just cut off the foliage, and leave the soil (and whatever is in it) in the greenhouse over winter? If these plants are from seed - will they survive this way - or is it a waste of time?? Hope this makes sense! Thanks.
